Magnehelic Gauge Centre Zero 50-0-50Pa

PAG-2300-100Pa

£178.00

Description

The Magnehelic gauge is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves. A single case size is used for most models of Magnehelic gauges. They can be flush or surface mounted with standard hardware supplied. Although calibrated for vertical position, many ranges above 250pa may be used at any angle by simply re-zeroing. However, for maximum accuracy they must be calibrated in the same position in which they are used. These characteristics make Magnehelic gauges ideal for both stationary and portable applications. A 116mm hole is required for flush panel mounting. Complete mounting and connection fittings, plus instructions are supplied with each instrument.
